Ha! This is neat trick. Actually, what I needed that for was to call an init-type function only once, and this technique is perfect for that kind of job. No extra symbols.
Thanks, John!

You can get similar behavior if you want a less general approach by doing something like this, using the word symbol as a variable:: foo ( x -- y )\ foo [[ 1 + ] unless t] change-global ;IN: scratchpad 1 foo .2IN: scratchpad 1 foo .1
